SELF-CLOSING ATTACHMENT FOR FAUCET Specification of Letters Patent.

Application filed August 12, 1913. Serial No. 7871:5550.

To all whom it may concern:

Be it known that I, AnoNmAM J COLLAR, a citizen of the United States, residing at Yreka, in the county of Siskiyou and State of California, have invented new and useful Improvements in Self-Closing Attachments for Faucets, of which the following is a specification.

This invention relates to a self-closing faucet attachment which is particularly constructed for application to a faucet, patent for which was issued to me October 8, 1912, No. 1,040,624..

The object of the present invention is to provide a self-closing attachment for this faucet which can be cheaply manufactured, easily attached, and which will automati-, cally return the handle to close the valve after it has been opened.

Another object of the invention is to provide means which will permit the valve to turn and grind upon the seat beforethe valve is opened and after it is closed, thus insuring a perfect water-tight seat at all times.

Further objects will appear hereinafter.

The invention further consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a central vertical section showing the application of the seltclosing attachment to a faucet- Fig. 2 is a front elevation of the attachment. Fig. 3 is a section of same on the line X-X, Fig. 1. Fig. 4 is the difierent positions of the valve handle. Fig. 5 is a View similar to Fig. 1, showing the position of the parts when the valve handle is in the dotted line position indicated at 24 in Fig. 4.

Referring to the drawings: A indicates a faucet casing provided with an inlet opening 2 and a suitable form of discharge bib 3, between which and the inlet opening 2 a suitable valve seat 4 is formed.

5 indicates a threaded valve stem which projects through the upper end of the easing, while the other end is provided with a valve 6 which is so positioned as to engage with the seat 1.

Slidably mounted, within the upper portion of the casing, between projecting lugs 7, is a nut 8 which is externally grooved, as indicated at 9, to fit the projections? the grooves and projections being provided for the purpose of preventing the nut from turning.

The novelty of the present invention resides in the self-closing attachment which is here shown jas consisting of a cylindricalshaped casing 10, appropriately secured, as at 11, to the faucet casing cap 12. The upper end of/the valve stem is provided with a handle 13' which projects through a cutaway portion 10 formed on the upper end of the casing 10.

Mounted upon the handle 13 and valve stem 5 is a cap 14. which extends into the casing 10 and which is suitably secured in position upon the stem and handle by a screw 15. The forward face of the cap 11 is provided with an opening 16 through which the handle 13 extends and will thus be movable in unison with the stem and handle of the valve.

The lower portion of the casing 10 is pro 4 vided with an inwardly projecting lug 17, and surrounding the upper end of thestem 5, within the casing 10 ina position where one end is secured by the lug 17 and the other by the handle 13, is a coil sprin 1% which is so positioned as to normally hol the valve handle in the full line position indicated in Fig. 1, which position is limited by a shoulder 19 formed by cutting away the upper portion of the casing 10 to produce the cutaway portion 10 previously men; tioned. The extreme o posits position of the handle 13 is limits by a shoulder 20 similarly formed.

' The operation of the sell-closing and rinding attachment here shown will he as the valve 6 will be entirely seated to close the flow of water through the faucet. The

end of the sliding nut 8 will, when the top valve 6 is seated, be distance below a packing ring 22, which is held by the faucet casing cap 12 as shown in Fig. 1. By turning the handle 13 shown in Fig. 4., to the dotted line position, indicated at 23, it will be seen that the nut will be elevated where it engages with the pacln'ng ring 22 which latter acts as a stop; at the same time the valve 6 is permitted to turn and grind against the seat, as no movement of the valve stem in a downward direction has taken place. Furthermore, the ten sion of'the spring 18 interposed between the faucet cap 12 and the handle 13, together constantly ,be maintained by full.

with the water pressure upon the lower face of the -valve, will have a tendency to force the valve with sufficient ressure against the seat to cause=tl1e desired grinding or wean ing action as the valve is turned. However,

the moment the nut 8 has reached the upper the packing ring 22. The valve will thus open sufliciently to permit a suitable flow of water through the discharge bib.

By turning the valve handle from the full line position, indicated in Fig. 4, to 'the dotted line positiom'indicated at 24:, suifie cient torsion'strain or twist is transmitted to the springlS to immediately return the handle 13 to its normal position, indicated lines in Fig. 4; the first quarter of the return'movement acting to close the valve,-- v vlnle the last quarter movement from the position indicated at 23, causes the valve to tuin'and grind on the seat. 'A grinding or turning movement is thus imparted to the valve both when opening and closing the valve and a perfect water-tight seat will until the valve casingiscompletely worn.

One side of the cut-away upper end of the casing 10 is sufliciently inclined, as indicated at 25, to permit the handle with connected stem to move in a downward direction to-open the valve when the handle is turned from the dotted line position, indicated at 23, to the full cated at 24:. Any place through drained oil through an opening 26'formed in thelower portion of thezcasin 10. A. steel'spring may thus be employ for the purpose of returnin the valve to the closed position without 1111 no exposure to moisture. Any suitable packing, of course, may be provided between the ring 22 and the faucet cap 12 to reduce this leakage, possible. a

The attachment here shown is simple in construction, neat in appearance, tive and reliable in 'act1on. The grinding movement imparted to the" valve at each turn of the handle produces a perfect contact between the valve and seat, and leakage leakage which might take through the valve is thus entirely obviated.

Having thus described my invention, what I claim and desire to ent, 1s:
